Throttle grip sticking
Ever since I put my new bars on the throttle has been sticking. I didn't put any lube inside the throttle grip so I figured that ust be the problem. I looked up what I should use in the shop manual and it said to use graphite. So I took offthe grip and coated it with graphiteand all it did was make a huge mess. I put it back together, adjusted the cables, and made sure the throttle adjsuster was all the way loose. It actually seems to have made it worse.
Somebody said you can screw up the inside of your throttle grip. What happens to it?
Does anybody has a stock throttle grip they want to get rid of? I'll pay shipping and handling.
Anybody have any ideas why the throttle isn't snapping back like it should?

A couple of things to check.
Take the top loose from the switch housing and make sure the cables are in the groove and not bound up where the ends seat into the sockets.
Are you using a grip/throttle combo (similar to stock) or are you using a throttle tube and glue-on grips?
If they are glue on, check that glue didnt get between the tube and handlebar.
If all is well with these two, the problem is the cable or the return spring.
Check that the cable routing isnt bound or pinched.
If no, loosen the adjusters, form a funnel from tape around the sheath and spray WD-40 into the cable sheath.
Adjust the cables back to proper tension. Its very eady if you havent done it. Im sure you have.
Finally, if the problem still exists, take off the AC and check the throttle return spring. It should function flyidly without binding or a jerky motion. If its defective, you'll need a manual to show how to replace it.

I'm using the stock grips..I never took off the grip from the tube. (I didn't even know they came apart) I checked the cables and they are in the grooves. The throttle spring seems to be ok..it springs back. I know it's something I did when I did the bar install because it worked perfect before. I used a dry spray graphite and that seemed to gunk it up more then help. HD recommends graphite but I wonder what others are using as it real makes a mess and was hard to get off the few splats that hit the frame.
I still ride it, but I need to fix it as it can't be as safe.

Are the bars higher than stock, if so are the cables pulled tight.
Does the throttle move freely on the bars without the cables attached, or is it binding.
If it moves freely on the bars without the cables attached then the problem must be with the cables.
If not it must simply be the bars are slightly thicker than the ones you took off.
Can't think of anything else it could be if the problem started when you changed the bars, then the problem must be the new bars.

I'd be willing to bet that something got between the throttle and handlebar. It doesn't take much.
BTW, the stock throttle/grip isn't meant to come apart. I only asked because I use a throttle tube. It is essentially the same thing but without a grip. It allows users to install any number of glue-on style grips.
When I installed my bars recently, I also changed grips. I used 3M spray adhesive that I sprayed down into the grip. Then I slid the grip over the throttle tube. I should have let it dry, but it was the last step and I wanted to ride. Little did I know that the throttle tube has a tiny hole in the outboard end. A small amount of partially cured adhesive got between the throttle and the bar, and turned into tiny rubber ***** that made throttle action become stiff. 15 minutes into my ride (and 20 miles from my house
), my throttle felt like the cable was all bound up. Instant cruise control. I got home, took it apart and cleaned the inside of the throttle and the outside of the bar. A little graphite and I'm still enjoying a very smooth throttle.Here's what a throttle tube looks like. Your stock throttle is basically a plastic version of this with the grip built in.

The bars are slightly higher but with the pullback they have almost exactly the same slack that it did with stock. I was thinking the chrome plating might be a tad thicker then the stock and that could be causing it. The throttle turns pretty well without the cables attached but it sure doesn't feel like glass. Hard to compare to stock since I never tried the grip without the cables hooked up before I change the bars.
Has anyone ever heard of screwing up the inside of the throttle grip itself?

I use dry graphite in a small tube (meant for door locks.)

rooti, is the throttle thumb screw too tight? It seems to be a common problem after grip change, ppl always overlook.
